SOAP-BUBBLE FOUNTAIN.

SPECIFICATION forming part of Letters Patent No. 548,477, dated October 22, 1895.

Application tiled November '7, 1894. Serial No. 528,156. (No model.)

To all whom t may concern.-

Beit known that I, SAMUEL H. TACY, a citin zen of the United States, residing in the city and county of New York, State'of New York, have invented an Improvement in Soap-Bub ble Fountains; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus for the continuous form ation of soap-bubbles and a mechanism connected therewith.

It consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in whichm Figure 1 is a sectional elevation of an apparatus designed for the purpose. Fig. 2 is an illustration showing its action. Fig. 3 is an enlarged view of the nozzle-float and adjustment.

The object of myinvention is to provide an automatically-regulated apparatus for the continuousproduction ofsoap-bubbles, means for keeping up the supply of material as fast as exhausted, means for regulating the position of the nozzle with reference to the quantity of liquid in the bowl or fountain, and also to regulate the size of bubbles produced,

and means for illuminating the same.

In the construction of my fountain I employ a bowl or receiver G, which may be made of any suitable material, preferably of glass. It is supported by a tubular column g, also preferably of glass, and this is connected at thelower end with a tube X, through which air is admitted and passes up throughv the tube g into the receiver G.

Around the tube Xis xed avreste-tank T, and above this waste-tank is iixed a catchbasin R, which may rest upon the tank T and by means of braces or supports therein assist in supporting and steadying the tube g. Above the catch-basin R is a hood L, surrounding the tube g and having within it a rotary disk M, provided with differently-colored glass plates at intervals around its circumference for the passage of light from the electric or other lights t, which are situated beneath the disk M. The disk M is caused to rotate by means of a pulley a turning freely around the vertical tube g and carrying the disk with it. A belt a2 passes from any source of power around the pulley aand thus rotates the disk at any desired rate of speed.

Any suitable well-known mechanism may be substituted to produce the rotation of the disk.

The hood L maybe transparent, or if made of metal or other opaque substance it may have glass disks s in line above the electric lights through which the differently-colored lights from the disk M Will be thrown up- Wardly.

Connected with the upper end of the tube g'is a flexible or movable tube K, having a check-valve H, through which the air passes into the tube. The upper end of the tube is supported by a i'loat m and has a nozzle dipping below the surface of the liquid, which is contained Within the reservoir U. The oat m rises and falls upon the surface of the liquid, so as to retain the nozzle at a constant depth below the surface, and the nozzle is also adjustable with relation to the float, so that it Will dip into the liquid to a distance which will produce the best results when in operation.

ln order to supply the receiver G with the soap solution from which bubbles are to be made, I employ a reservoir A, situated above the level of the receiver G and adapted to contain a supply sufiicent for any desired length of time. From this reservoira pipeE leads into a smallerinterniediate reservoir C, and from this a second pipe H', of less capacity than the pipe E, discharges into the receiver G.

Bis a valve in the pipe E. The stem of the valve is connected with an armature c, which is moved by an electromagnet d when the latter is energized.

F is a circuit-breaker oi' any of the usual or ordinary forms of construction, and through this a current of electricity is passed to the electromagnet d, so that when the electromagnet is energized the armature c will be drawn up and will open the valve at B, thus allowing the solution to flowfrom the reservoir A into the receiver G. A spring b, acting upon the stem of the valve, will close the latter whenever the current of electricity is cut oi.

In order to open or close the circuit at F, I'

ICC

breaker, and this has suspended from its lower end atuoe or slide o, connected with a float m, resting upon the surface of the liquid inthe receiver G.

Zis a vertical rod or guide extending up into the tube o through the float n and serving to keep these in their proper position as they rise and fall.

\Vhenever by the operation of the apparatus the supply of the solution in the receiver G falls too low, the float n, descending withit,willeventuallypuliupon the cordp and draw the leverf down until it tnakescontact with the other member of the circuit-breaker, when a current of electricity passing through the electromagnet d will act to open the valve B, as previously described, and liquid will liow through the pipe, filling the smaller reservoir C, and thence liowing through the pipe H into the receiver G until the liquid therein is raised to near the proper point, when the float n, rising, will release the leverartnf, and by means of a spring ff' the lever-artnfwill be thrown up and the circuit will be broken. The valve at B will then close and the flow of liquid from the reservoirA will cease. The reservoir C will then discharge what remains in it through the smaller pipe H', thus filling the reservoir C to the desired height.

D is a gas burner or heater of any description having a lever u connected with its controllingcock, and this isconnected by a cord with the armature c, so that when the arma ture is moved in one direction it turns on the light, and this acts to heat the liquid in the reservoir C and passing through it before itis delivered into the receiver G. This is done because I have found that the solution works better when slightly warm. The current of gas is cut off again when theliquid ceases to flow by the operation of the rod connecting it with the armature.

The operation will now be as follows: The receiver G being filled with a solution of soap dissolved in water to the proper strength, air is supplied through the pipe X by any suitable air-forcing mechanism. The air flowing up through this pipe, the tube g, and the nozzle of the pipe K is discharged just beneath the surface of the liquid sufficiently to form bubbles, which first till the cylindrical receiver, rising up and flowing over the edge of the receiver, each bubble being followed by a succession of others as long as the air-current is continued. These bubbles flowing over the edge of the receiver cling to the side and also the side of the tube g, flowing thence downward upon the hood L, which, serving as a sort of stop, causes them to pile up in a pyramidal form, and as they accumulate they gradually flow over the edge into the catchbasin R and thence eventually descend into the tank T, where, becoming dissolved or returning to the watery condition again, the liquid may be drawn off through a cock y and again returned to the reservoir A. ln the continuous flow of the bubbles the size can be regulated to some extent by the depth to which the nozzle of the air-tube is immersed in the solution. The deeper it is immersed the smaller the bubbles will be. In practice the bubbles are not of a uniform size and the larger ones will separate from the smaller, flowing over one side of the receiver G, while the smaller ones flow over the opposite side, there being a gradual decrease in size from the larger ones upon one side to the smaller ones, which become so small as to have an opaque and whitish appearance, while the llarger ones are clear, and, crowding together,

their meeting faces will be tiattened, so that they take polygonal shapes, piling up in this form in varying fantastic shapes in the hood L and the catch-basin R. \Vhile this is going on the disk M is rotated and the variouslycolored lights are alternately thrown upward through the mass of bubbles, producing any variety or combination of colors, which ingenious'arrangements of the colored glasses will effect.

Vhile I have here described an apparatus by which these results may he produced, it will be manifest that various modifications of the appliances may be made without departing from the main features of the invention.

If desired, several receivers G may be arranged around or with other desired relation to a central one and branch air-pipes leading to each with appropriate connections allow of varying and beautiful combinations.
